If the whole purpose of our existence is just to get saved, then why doesn't the Lord just take us home to Heaven the minute we get saved?--because once we're saved, we have a job to do! We have a responsibility! There are a lot of other people who need to know Jesus, and He has given us a commission: "And He said unto them, Go ye into all the World, and preach the Gospel to every creature!" (Mk.16:15)
Jesus alone saves, but He doesn't want to save you alone. He wants to save the whole World, but in order to do that He needs us to tell others about His Love, to give His Love and message of Salvation, the Gospel, the Good News, to the whole World. (See Rom.10:13-15.)
Jesus said, "Even as My Father hath sent Me, so send I you." (Jn.20:21) He says this still to His followers of today, calling them to give their lives daily in loving concern and care for others, to share His heart and Love with those who are seeking for "the Way, the Truth, and the Life." (Jn.14:6)
Will you answer His call? Will you love and do what you can to win souls? Will you spread the Word, spread the Message, spread His Love?--God will bless you as you obey His Call!
